SULKY-PLOW.

SPECITFZCATICN forming part of Letters Patent No. 329,731, dated November 3, 1885.

Application filed June 9, 1885. Serial No. 168,199,.v (I\"o-m0del.)

To aZZ whom it may concern.-

Be it known that I, LEwIs Games, a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have invented a new and useful Improvement in Sulky- Flows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to an improvement in sulky-plows.

The object of my invention is to provide in a sulky-plow such construction of parts and arrangement by which the operator may have control of the plow during its progressive movement. A further object consists in such adaptation and location of a seat for the operator that his weight may be utilized in raising or otherwise controlling the plow. Afurther object consists in a rectangular main frame-section provided with spindle-bearing quadrants that vibrate about a center'and are adapted for adjustment with the frame. A further object is to provide a center or pivotal point about which a spindle-bearing quadrant may be vibrated that can be adjusted during the progressive movement of the plow. A further object is to provide a toothed sector integral with a flanged corner-support for the main frame and a handlock lever and linkconnection with a sliding spindle bearing quadrant. A further object is to provide a base or support for a hand-locking lever that is integral with a flanged corner-support for the main frame. A further object consists in the combination of the-tongue-frame section hinged to the main frame, and adapted at its front end for engagement with a tongue, which in turn is adapted for such engagement, and provided with means for lateral adjustment. A further object consists in providing an'adjustable foot-lever,pivoted to the tongue-frame section and extending through a bell-crank and linkto a standard,which in turn is ad;- justable with a plate attached to the plowbeam.

WVith these objects in view my invention consists in certain features of construction and combination of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a rear view in elevation of my improved sulky plow, in which are shown the several parts in their respective places when the plow is operated. Fig. 2 is an enlarged perspective of the spindle-bearing quadrantand a section of the main frame, showing the relation of the spindle to the quadrant and the manner of connection with the frame. Fig. 3 is a side elevation with wheel removed and the rear end of side brace of tongueframe removed, so as to show more clearly the parts as they will be referred to and explained herein. Fig. 4 is a view showing the connection of the tongue with tongueframe and the means of adjust ment. Fig. 5 is a view of the foot-lever connection with the bell-crank. Fig. 6 is a perspective of the beam-clamping plate and adj ustable standard. Fig. 7 is an enlarged view in perspective of a detached portion of the main frame with corner-iron and lock-lever attached, and a portion of the tongue-frame with toothed sector attached. Fig. Sis a similar View of the opposite corner of the main frame, in which is shown the corner-iron, the connection with the tongue-frame, the toothed sector, the hand lock-lever, and linlcconnection with the spindle-bearing adjustable quadrant.

The frame is made, preferably, of two flat metal bars,A, bent in the form shown in Fig. 1,with the ends abutted together at a and bolted to the hinge F, hereinafter described, and a round bar, A", joined to the ends of the respective bars A. The clamps B and B that secure the parts A and A, are made in halves and have round seats d at one end for embracing the bar A and flat seats d at the other end for grasping the flat bars. The spindle-bearing quadrant B may be bolted to the frame-bar A, as shown in Fig. 2. The bolt 0, the pivotal point around which the plate B, with the wheel-spindle C attached, may be vibrated for the purpose of adjustment, and the bolt 0 may be passed through one of the holes in the arc of the plate and the frame to secure it in the'desired position. This adjustment may be made at different points on the framebar A by moving the plate on the bar and securing it by the same integral with the quadrant-plate or separate,

and placed at any desired point on the plate between the pivot and the periphery.v By,

vibrating the plate and spindle about the pivotal point any adjustment of the wheel may be had that is required. The spindlebearing quadrant -D is mounted on a sliding plate, E, having longitudinal side ribs that embrace the frame-bar A, and the ears 6 e e e to which the quadrant is attached by the through bolts ff f f as shown in Fig. 8.

The quadrant-plate is-provided with a pivotal point at the upper rear corner, a circular or segmental slot in the rear lower corner, and .two rows of holes, each on a line of different diameter from the pivotal point. By removing theboltsf and f from the hole and slacking the bolt f the quadrant-plate and spindle may be vibrated about the pivotal bolt f and secured at the desired position of adjustment by inserting the bolts f and f. The wheels G are mounted on the spindles O and secured by the nuts 9 g. H of the main frame is provided with flanges m,

that embrace the frame, and is secured there to by through-bolts, and is further provided with ears Z, that extend forward as a hingesupport for the tongue-frame K, and is further provided with a toothed sector, L, and a support for a hand-lock lever, M. These parts are of metal and preferably integral. The hand-lever M is pivoted to the sector in a suitable manner, and a spring-dog, h, engages the notches on the sector, and .is operated by the hand-lever M there extends a link, J, which is connected to the sliding plate E by the bolt is, as shown in Fig. 8. Corner iron or support N is provided with flanges '.to embrace the frame, lugs or ears Z extending forward as a hinge and support for the tongue-frame K, and a hand-lever, P, formedintegral and preferably of malleable iron. A toothed sector, 0, is bolted to the tongue-: frame K and hinged to the corner-piece'N. The hand-lever P is provided with a spring dog, 7', connected by the rod .9 to the bellcrank handle t, thus forming a locking mech anism by which the tongue-section and the mainframe section may be locked and held in any desired position.

mounted with a suitable hinge-piece, F, by

frame and the lap-plate a. from a point near the front end of this center piece at an angle of about forty-five degrees to the hinges R, provided on the corners of the main frame. The tongue T may be attached to the tongue-frame by the adjustable The. cornersupport 1 and avoiding obstructions. the lever h, of the bell-crank variety,-and' connected with the dog by the rod i. From clamping-plates U and V, rigidly attached to thetongue by the bolts 1 and 2, and pivoted on bolt 3 and adjusted on bolt at by the engagement of the notches with the bolt-head, which is adapted for such engagement, the object of which will be hereinafter explained. The spring for the operators seat is attached to the center-piece of the tongue-frame, and so located as to bring the seat in front of spin.- dles of the supporting-wheel, that the weight of the operator may be utilized as a balancein raising the plow.

To adapt'the main frame to a high or low beam plow,the spindle-bearing quadrants may be vibrated about their pivotal points and adjusted as may be desired.

The plow may be attached to the main frame in the following manner: Plate 13 has upwardly-proj ecting angular ribs, and similar ribs depend from plate B. When these plates are in position, the respective ribs register,

and between the opposing central and angular parts of the ribs there is room for the bar A. The plow'beam X is placed above the plate B between it and the clamping-plate W, and secured by boltsextending up through the plates B and B on either side of the beam and through the clamping-plate W, that rests on the top of the'beams, and are provided with :nuts, by means of which the parts are securely fastened. The collars e and n on the bar A are provided with set-screws, and may be used to adapt the plates to either a right or left hand plow. With this construction,

the plates may swing in either direction, as on a pivotal point, so that the plow may as sume any position required in turning corners The foot-lever R is provided at one of its ends with a suitable rest for the foot. The other end is adapted for adjustment with a bell-crank, S,which is pivoted to the tongue-frame, and provided with a serrated disk, D, to which the foot-lever may be adjusted and secured by the through-bolt M. The upper end of the bell-crank S is connected by a link, T, to the upper end of the arm U, the lower end of which is provided with a serrated disk, which is adapted for engagement with a similar disk on the beam-plate W, and may be held in such adjustment by the through-bolt When in operation, the main frame will project from the tongue-frame on an angle of about thirty degrees. By a depression of the foot-lever the plow may be made to more readily enter 7 ,3 hard ground; or to release the plow from ob- The hinged tougueframe sectlon is com-.

posed of the following parts: a center-piece, S,

structions a. downward movement of the lever through its connections will cause the plow to move backward as well as upward. To further elevate the plow, release the lock-lever P from the toothed sector, and the weight of the operator will raise the plow until the main frame has reached a line about parallel with the tongue-frame.

To regulate and adapt the plow to the ground and conditions that may be met duringits progressive movement, the lever M may be moved 7 forward or back, and through its connection with the sliding plate E will move the wheelspindle on the main frame and secure the desired adjustment. For further adaptation the tongue may be moved at its point of connection with the tongue-frame and adjusted therewith.

Having thus fully described the nature and object of my invention, what I claim, and desire to secure by Letters Patent, is

1. In a sulky-plow, a spindle-bearing quadrant adapted to vibrate about a pivotal point mounted on a sliding plate and for adjustment thereto, as described, and for the purpose set forth.

2. In a sulkyplow, the combination of the adjustable spindle-bearing quadrant, the sliding plate, and the connecting-link with the locking hand-lever, as described, and for the purpose set forth.
